So now I've seen governance proposals floated from two major alts of cycles past about selling the native token held in treasury to acquire BTC

I don't care all that much about the Cardano proposal...and frankly there's like 17 people in the world that have actually used ADA before, so they probably also don't care, but I am a lot more curious about the Polkadot proposal.

~500k DOT being put up for tBTC acquisition. It's really not a ton in the grand scheme of things...like what $2m? From a pragmatism standpoint, I can see a scenario where they want to use it to farm DeFi yield and beef up the treasury some more, and that's better than idle coins. It would also make sense to highlight their flagship DeFi protocol in Hydration.

At the same time, if foundations are starting to liquidate treasury tokens for BTC, will that cause concern or delight for stakeholders in their ecosystems? I'm really not sure. If it was a treasury that got returned to holders eventually (like crypto treasury companies) that might be more palatable, but when the native token holders don't have any claim on the treasury, I'm undecided what the outcome would be.

At the end of the day it's mostly a wash because $2m isn't a large portion of the warchest for these size chains, but still interesting to see more discussion on the topic.
